Objectives
In the context of increasing environmental concerns and
resource scarcity, it is essential to evaluate the long-term
sustainability of traditional linear models, particularly in
industries that consume significant resources and generate
substantial waste. The team at Mamoru has recognised this
challenge. It has taken proactive steps to enhance its repair
program, establishing a closed-loop system designed to
minimise the outflow of waste to external waste management
companies.

Table 1. Average Number of Disposed Purifiers (Before)

In addition to identifying the quantity, the team also categorised
the types of waste generated from each disposed ECOM 030+
purifier. This allowed us to calculate the total monthly waste
generated from purifier disposal. The calculation showed that
an average of 1749kg is being disposed of annually, which
leads to an annual carbon emission of 10.25 tons of CO2.
The team dismantled one purifier, weighed the parts, and
estimated the weight of the different materials.

By conducting a thorough analysis of malfunctioning air
purifiers, the team has determined that a significant portion
of these units can be effectively repaired and returned to
customers. This conclusion aligns with the team's technical

expertise and ability to extend the lifecycle of units and reduce
unnecessary disposal.

The proposed solution aims to achieve a substantial reduction
in disposed units, targeting a 50% decrease. This goal is
expected to have a positive impact on the environment,
translating into an estimated reduction of 5.2 tons of carbon
emissions annually. By implementing this strategy, Mamoru

also demonstrating his leadership in responsible corporate
practices.
